xml操作的类及常用函数的使用例子

CXMLFile xmlfile("DATA.xml"); CString parentpath; xml写 parentpath = "Data/ParameterA"; xmlfile.SetNodeValue(parentpath,"A");//在Data/ParameterA下添加结点A xmlfile.SetAttribute(parentpath,"A","I","5");//设置A结点的属性I为5 xmlfile.SetNodeValue(parentpath,"B","6");//在Data/ParameterA下添加结点B,其值设为6 xmlfile.save("DATA.xml"); xml读 std::string cattributevalue; cattributevalue = xmlfile.GetAttribute(parentpath,"A","I","0");//读取Data/ParameterA下结点A的属性I的值 默认值为0 CString cattvalue; cattvalue = cattributevalue.c_str(); cattributevalue = xmlfile.GetString(parentpath,"B","0");//读取Data/ParameterA下结点B的值 默认值为0 xmlfile1.DeleteSetting(parentpath + "/A",""); //删除A结点及其子结点 xmlfile1.save("DATA.xml");
